Exclude Spring Request HandlerInterceptor by Path-Pattern

Question

I know we can map different url to different interceptor, or we can map multiple url to single interceptor too. I am just curious to know if we also have exclude option. for example if I have 50 url mapping in application and except 1 mapping I want to call interceptor for all so rather than writing configuration for 49 mapping can I just mention * and one exclude to the 50th url?

HandlerInterceptors can be applied or excluded to (multiple) specific url's or url-patterns.

See the MVC Interceptor Configuration.

Here are the examples from the documentation

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LocaleInterceptor());
        registry.addInterceptor(new ThemeInterceptor()).addPathPatterns("/**").excludePathPatterns("/admin/**");

        // multiple urls (same is possible for `exludePathPatterns`)
        registry.addInterceptor(new SecurityInterceptor()).addPathPatterns("/secure/*", "/admin/**", "/profile/**");
    }
}

or using XML config

<mvc:interceptors>
    <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/>
    <mvc:interceptor>
        <mvc:mapping path="/**"/>
        <mvc:exclude-mapping path="/admin/**"/>
        <bean class="org.springframework.web.servlet.theme.ThemeChangeInterceptor"/>
    </mvc:interceptor>
    <mvc:interceptor>
        <!-- intercept multiple urls -->
        <mvc:mapping path="/secure/*"/>
        <mvc:mapping path="/admin/**"/>
        <mvc:mapping path="/profile/**"/>
        <bean class="org.example.SecurityInterceptor"/>
    </mvc:interceptor>
</mvc:interceptors>
